We built a two story farm home several years ago and I 'tried' to plan ahead. Hard with tech, but I tried.
The center closet is a wiring closet. Switches, Access points, wiring points, etc. The top half if hardware, the bottom half is standard closet. All items are fanless and there are louvers on the door for air cooling. Heat has never been an issue.
I pre-wired the house with multiple RG-6 cables for our satellite tv (We live away from town) with multiple outlets in the rooms
I wired the house with CAT 6 cables
(I wish I could have done fiber back then)
Outlets in the room alternate circuit breakers. If a breaker trips, only half of the outlets lose power.
Built in several wire paths for surround sound setup. If the furniture is rearranged, the speakers can move and there are no cables running along the floor or walls
There are speaker lines run through the house, the 'main' stereo system can provide entertainment to several rooms
The walls have several wiring boxes on them, but it is SO WORTH IT.
We do have a small home 'windmill' for power generation. It is pre wired to the well pump for water in a power outage, the refrigerator and our four freezers (home grown beef, pork, goat, chicken, turkey, lamb plus halibut and salmon from fishing) and frozen veggies can be connected when needed. We have a "clean" burning wood stove for heat and cooking. Outside lighting around the house and paths around the barn are solar powered low voltage lighting runs
